Couple of questions about DC-Dc charging
I've been thinking about adding a DC-DC charger now that I've added 400 amp hours of AGM batteries. There are lots of useful posts but I haven't run into a couple of things I'm curious about. One ...

thats great, there is a lot of information in your posts once you filter through it

Unless an RV is "Hot Seat" operated, meaning driven day and night for weeks on end, any multi-stage voltage "steps" are ludicrous. The rig is simply not driven long enough in hours for voltage manipulation to matter. We're not talking about a manual wheeled battery charger here. Alternators are voltage regulated.
so lots of time people do drive for 4 to 6 long days to get to a destination is that a different outcome? and I know in this case the poster has AGM, which I admidt I did miss as normaly when I see DC to DC chargers mentioned it is in a LFP aplication, and I do believe with LFP batteries the outcomes would be different than with Flooded or AGM batteries.

It wouldn't see correction from 14.0 volts to say 14.4 voltage inside of eight hours of campsite continuous engine operation. Read this again. Still with me?
If a DC converter was designed for say 60 amp operation, then it presents a different issue. But it isn't and it doesn't.
well they do make 60 Amp and 80 Amp versions, so if you went with one of thoes how would it varry the results?
